Make sure all your custom domains navigate properly to your app to be able to verify your domains

Enable Let's Encrypt

Restart your app

Let's Encrypt is still in beta and certain rate limits apply. This means that we cannot provide SSL certificate for your app's domain at *.evennode.com. However the certificate will be issued for all your custom domains. Just make sure your custom domains redirect properly to your app to verify ownership of the domains.

Let's Encrypt SSL certificates are supported on majority of operating systems and browsers. However please note that as of writing this blog post there are certain issues on Windows XP with IE and Chrome, Blackberry OS 6, 7, 10 and Android 2.3.5.
